If you want Antarctica without two days each way on the Drake Passage, you'll end up comparing two companies: Antarctica21, which built its business on fly-cruises, and Quark Expeditions, the biggest name in polar travel, which runs its own Antarctic Express program.
Both start in Punta Arenas, Chile. Both fly to King George Island in the South Shetlands, where you board your ship by Zodiac. Both run eight-day trips. The differences are in the ships, the group size, the flight record and the price.
Short version: Antarctica21 wins on group size, flight experience and entry price. Quark wins if you want a bigger ship with more space, a parka to keep and Quark's wider choice of one-way routes.
Quick Answer
- Pick Antarctica21 for the smallest groups (up to 88 guests), the longest flight record (since 2003) and the cheapest way in (Antarctica Express from about $5,000).
- Pick Quark for a larger ship with more public space, an expedition parka you keep, and pre- and post-trip hotel nights in Punta Arenas included.
- Price: 8-day Antarctica21 Classic from about $15,995 (Magellan Explorer); Quark's 8-day Fly the Drake from about $17,591 (World Voyager).
- Same risk on both: weather at King George Island can delay flights by a day or more. Build in a buffer and insure it.

The Basics
2. How the Fly-Cruise Works
Same route, same airstrip, same weather.
Both trips follow the same pattern. You spend a night or two in Punta Arenas for a briefing and gear check. On flight day, you take a charter plane south over the Drake Passage to the gravel airstrip on King George Island. The flight takes about two hours. The same crossing by ship takes about two days each way.
From the airstrip, it's a short walk to the shore and a Zodiac ride to the ship. You then spend several days in the South Shetland Islands and along the Antarctic Peninsula, with landings and Zodiac cruises twice a day when weather allows. At the end, you fly back the same way.
The trade-off is the same on both. You save four sea days and almost all the seasickness risk, but you pay more per day, and the flight depends on clear weather at a remote airstrip. If you're prone to seasickness, it's often worth it. See our seasickness remedies for the Drake Passage if you're still on the fence.
Ships
3. Ships and Group Size
The biggest practical difference between the two.
Antarctica21 caps air-cruises at 88 guests. Magellan Explorer is a purpose-built expedition ship. The new Magellan Discoverer, debuting for 2026–27, is a polar class 6 ship with hybrid-electric engines, and every cabin has a private balcony. With 88 guests, everyone can usually land at the same time, so you're not waiting your turn on the ship.
Quark runs its fly-cruises on World Voyager, an all-balcony ship of about 170 guests, and Ocean Explorer, which takes 138. That's still small next to big-ship cruises, and it means more lounge space, more cabin choice and a bigger expedition team. But IAATO rules limit how many people can be ashore at one site, so larger groups often land in rotation.
| Ship | Company | Guests | Note |
|---|
| Magellan Explorer | Antarctica21 | Up to 88 on air-cruises | Lowest-priced A21 ship |
| Magellan Discoverer | Antarctica21 | Up to 88 on air-cruises | New, hybrid-electric, all balconies, PC6 |
| Ocean Explorer | Quark | 138 | Smaller Quark option |
| World Voyager | Quark | About 170 | All-balcony; Quark's 2026–27 fly-cruise lead ship |
Flights
4. Flight Record and Weather Delays
The question to ask before you pay either company.
Low cloud, fog and strong wind at King George Island can hold flights on the ground. When that happens, you wait in Punta Arenas, sometimes for a day or more.
Antarctica21 publishes its record. From 2003 to March 2023 it flew 274 flights over the Drake. About 78% left on schedule, and only one was cancelled outright; those guests sailed back instead. If guests can't reach Antarctica within four days, the company offers alternative activities or a full refund.
Quark doesn't publish a comparable flight record on its trip pages. That doesn't mean it's worse, only that you should ask for its weather contingency terms in writing before you book.
Protect the trip: On either company, book flexible flights home, add a buffer day, and carry insurance with travel delay and missed connection cover. Our
Antarctica travel insurance guide covers what to look for.

Plan My Antarctica Trip5. Itinerary Options Beyond the 8-Day Trip
Quark has more one-way options; Antarctica21 has the cheapest short trip.
| Trip | Company | What it is |
|---|
| Antarctica Express | Antarctica21 | 6 days; fly one way, sail one way; Nov and March only; from about $5,000 |
| Polar Circle Air-Cruise | Antarctica21 | Flies in, then sails south across the Antarctic Circle |
| Antarctica & South Georgia | Antarctica21 | Fly to Antarctica, then sail on to South Georgia |
| Fly South, Sail North | Quark | Fly in, sail the Drake back to Ushuaia |
| Sail South, Fly North | Quark | Sail from Ushuaia, fly out to Punta Arenas |
| Crossing the Circle | Quark | Fly-cruise that heads south of 66°33′S |
One-way trips save money and halve the Drake. They're a good middle ground if you want the crossing story without four sea days.
Price
6. Price and What's Included
Antarctica21 starts lower; Quark bundles more extras.
On the like-for-like 8-day trip, Antarctica21's Classic on Magellan Explorer starts about $1,600 below Quark's Fly the Drake on World Voyager. Antarctica21's new Magellan Discoverer is the most expensive of the four ships, at about $23,795, because of its all-balcony cabins.
| Included | Antarctica21 Classic | Quark Fly the Drake |
|---|
| Round-trip charter flights | Yes | Yes |
| Punta Arenas hotel | 2 nights with breakfast | Pre- and post-trip nights with breakfast |
| Meals on board | Yes | Yes |
| Drinks | Wine, beer, juice and soft drinks | Select beer, wine and cocktails |
| Expedition parka | Not listed | Yes, to keep |
| Boots | Loaned | Loaned |
| Kayaking | Paid add-on (max 20 guests) | Confirm when booking |
| Welcome dinner | Yes, at Explorers House | Not listed |
Neither price includes international flights to Punta Arenas, insurance or gratuities. Add those, and both trips land well above the headline fare. Our all-inclusive trip cost for two shows how the total adds up.

Frequently Asked Questions
Is Antarctica21 better than Quark?
For a fly-cruise, Antarctica21 is usually the better pick for small groups, flight reliability data and price. Quark is the better pick if you want a larger ship, more inclusions and more one-way route options.
How much does an Antarctica fly-cruise cost?
For 2026–27, Antarctica21's 8-day Classic starts at about $15,995 per person and Quark's 8-day Fly the Drake at about $17,591. Antarctica21's 6-day Express, which flies only one way, starts around $5,000.
What happens if the flight to Antarctica is delayed?
You wait in Punta Arenas until the weather clears at King George Island. Antarctica21 offers alternative activities or a full refund if guests can't reach Antarctica within four days. Ask Quark for its contingency terms in writing, and carry travel delay insurance either way.
Do you still cross the Drake Passage on a fly-cruise?
Only by air, in about two hours, on a round-trip fly-cruise. One-way options like Antarctica21's Express or Quark's Fly South, Sail North have you sail the Drake in one direction. Read how rough the Drake Passage really is.
Is a fly-cruise worth the extra cost?
If you get seasick, have limited vacation days, or are traveling with someone nervous about the crossing, usually yes. If you want the most time in Antarctica for the money, a sea voyage from Ushuaia gives you more days for less.
